Her romance may be "Covert" — but it's no secret that Piper Perabo is engaged!

The 36-year-old star of USA's spy drama Covert Affairs will marry Stephen Kay, a director and co-executive producer on the show, People reports.

"They're very happy," a source close to the couple tells the magazine. (Well, yeah, we'd hope so!)

Stephen, who hails from New Zealand, has also directed Get Carter and Boogeyman on the silver screen and episodes of Sons of Anarchy, Friday Night Lights, and The Shield on the small screen. He's an actor, as well, having acted in 31 installments of General Hospital, among many other credits.

Piper, meanwhile, is best known for Affairs but has plenty of big-screen roles on her filmography — including Coyote Ugly, The Prestige, and Looper.

We'll keep an eye on the mail for that wedding invite, Piper and Steven!
